Minecraft – Setting up a bukkit server for personal use on linux, isn’t installing properly, not sure why

linuxminecraft-bukkitminecraft-java-editionminecraft-java-edition-server

I have been trying to set up a bukkit server to run on localhost, so that I'd be the only one playing it.

I had someone on another forum help me get started by saying, basically, "Download the latest bukkit.jar from here, make folder and put that in it with a start.sh file that launches it (like this) and it will self populate the folder you put it in." The only difference in the start.sh I made was I listed the full path to the directory, and shrank the ram size to 1G. That didn't work, it wasn't populating the directory at all. So I tried loading the vanilla minecraft_server.jar, didn't work either.

I was told it could be a permission problem but it all looks fine to me. Below you can see the path to the craftbukkit.jar, aswell as the permissions from there. I'd appreciate any help, as I am very very new to any type of server setup.

ra@ra-desktop:~$ ls -al ~/.minecraft | grep Bukkit && ls -al ~/.minecraft/Bukkit 
drwxr-xr-x  2 ra ra    4096 2013-07-31 22:00 Bukkit
total 20896
drwxr-xr-x  2 ra ra     4096 2013-07-31 22:00 .
drwxr-xr-x 23 ra ra     4096 2013-07-31 00:54 ..
-rwxr-xr-x  1 ra ra 15249389 2013-07-30 08:54 craftbukkit-1.6.2.jar
-rwxr--r--  1 ra ra  6134331 2013-07-31 22:00 minecraft_server.1.6.2.jar
-rwxr-xr-x  1 ra ra       91 2013-07-31 22:00 start.sh

My start.sh looks like this now:

#!/bin/sh
 BINDIR=$(dirname "$(readlink -fn "$0")")
 cd "$BINDIR"
 java -Xmx1024M -jar craftbukkit-1.6.2.jar -o true

Here's the output though, being run from /home/ra/.minecraft/Bukkit:

Shouldn't this keep any population in the Bukkit dir?

There is an error in your BINDIR expression: you're using readlink incorrectly. From the man page for readlink:

If the given argument is not a symbolic link, readlink will print nothing and exit with an error.

So what you're feeding to dirname is an empty string, resulting in BINDIR being set to the empty string, which makes cd change to your home directory. You can confirm this by commenting out the java line and adding a line reading pwd just before it.

Change it to:

#!/bin/sh
 BINDIR=$(dirname "$0")
 cd "$BINDIR"
 pwd
 java -Xmx1024M -jar craftbukkit-1.6.2.jar -o true

… and it should work. Lesson: don't uncomment the "execution" line of a script until you've confirmed your cds are working correctly!
